IGR J08408-4503 in outburst observed by Swift
Abstract
Supergiant Fast X-ray Transients (SFXTs) are accreting HMXBs with OB supergiant companions showing outbursts in the soft/hard X-rays with an increase of 3-5 orders of magnitudes in the luminosity for a few hours followed by smaller amplitude flaring activity. We report on the analysis of the 2011 outburst of IGR J08408-4503 caught by Swift/BAT (15-150 keV) and followed up at softer energies (0.2-10 keV) with Swift/XRT. The spacecraft automatic slew and BAT/XRT simultaneous observations allowed us for the first time resolved broadband spectral analysis of the outburst emission for this source. We searched for spectral evolution and compare our results with those of IGR J16479-4514 time resolved spectral analysis.
